Description : Flowers Cracking Concrete is the first in-depth study of the forty-year career of Eiko & Koma—two artists from Japan who have lived and worked in New York City since the mid-1970s, establishing themselves as innovative and influential modern and postmodern dancers. They continue to choreograph, perform, and give workshops across the United States and around the world. Rosemary Candelario argues that what is remarkable about Eiko & Koma’s dances is not what they signify but rather what they do in the world. Each chapter of the book is a close reading of a specific dance that reveals a choreographic theme or concern. Drawing on interviews, live performance, videos, and reviews, Candelario demonstrates how ideas have kinesthetically and choreographically cycled through Eiko & Koma’s body of work, creating dances deeply engaged with the wider world through an active process of mourning, transforming, and connecting.

Description : Winner, 2019 ATHE Outstanding Book Award, given by the Association for Theatre in Higher Education Winner, 2018 Errol Hill Award in African American theater, drama, and/or performance studies, presented by the American Society for Theatre Research A new manifesto for performance studies on the art of queer of color worldmaking. After the Party tells the stories of minoritarian artists who mobilize performance to produce freedom and sustain life in the face of subordination, exploitation, and annihilation. Through the exemplary work of Nina Simone, Jorge Ignacio Cortiñas, Danh Vō, Felix Gonzalez-Torres, Eiko, and Tseng Kwong Chi, and with additional appearances by Nao Bustamante, Audre Lorde, Martin Wong, Assata Shakur, and Nona Faustine, After the Party considers performance as it is produced within and against overlapping histories of US colonialism, white supremacy, and heteropatriarchy. Building upon the thought of José Esteban Muñoz alongside prominent scholarship in queer of color critique, black studies, and Marxist aesthetic criticism, Joshua Chambers-Letson maps a portrait of performance’s capacity to produce what he calls a communism of incommensurability, a practice of being together in difference. Describing performance as a rehearsal for new ways of living together, After the Party moves between slavery, the Civil Rights Movement, the first wave of the AIDS crisis, the Vietnam War, and the catastrophe-riddled horizon of the early twenty-first century to consider this worldmaking practice as it is born of the tension between freedom and its negation. With urgency and pathos, Chambers-Letson argues that it is through minoritarian performance that we keep our dead alive and with us as we struggle to survive an increasingly precarious present.

Description : In Choreographing in Color , J. Lorenzo Perillo investigates the development of Filipino popular dance and performance since the late 20th century. Drawing from nearly two decades of ethnography, choreographic analysis, and community engagement with artists, choreographers, and organizers, Perillo shifts attention away from the predominant Philippine neoliberal and U.S. imperialist emphasis on Filipinos as superb mimics, heroic migrants, model minorities, subservient wives, and natural dancers and instead asks: what does it mean for Filipinos to navigate the violent forces of empire and neoliberalism with street dance and Hip-Hop? Employing critical race, feminist, and performance studies, Perillo analyzes the conditions of possibility that gave rise to Filipino dance phenomena across viral, migrant, theatrical, competitive, and diplomatic performance in the Philippines and diaspora. Advocating for serious engagements with the dancing body, Perillo rethinks a staple of Hip-Hop's regulation, the "euphemism," as a mode of social critique for understanding how folks have engaged with both racial histories of colonialism and gendered labor migration. Figures of euphemism - the zombie, hero, robot, and judge - constitute a way of seeing Filipino Hip-Hop as contiguous with a multi-racial repertoire of imperial crossing, thus uncovering the ways Black dance intersects Filipino racialization and reframing the ongoing, contested underdog relationship between Filipinos and U.S. global power. Choreographing in Color therefore reveals how the Filipino dancing body has come to be, paradoxically, both globally recognized and indiscernible.

Description : The Routledge Companion to Butoh Performance provides a comprehensive introduction to and analysis of the global art form butoh. Originating in Japan in the 1960s, butoh was a major innovation in twentieth century dance and performance, and it continues to shape-shift around the world. Taking inspiration from the Japanese avant-garde, Surrealism, Happenings, and authors such as Genet and Artaud, its influence can be seen throughout contemporary performing arts, music, and visual art practices. This Companion places the form in historical context, documents its development in Japan and its spread around the world, and brings together the theory and the practice of this compelling dance. The interdisciplinarity evident in the volume reflects the depth and the breadth of butoh, and the editors bring specially commissioned essays by leading scholars and dancers together with translations of important early texts.

Description : With its dynamic choreographies and booming drumbeats, taiko has gained worldwide popularity since its emergence in 1950s Japan. Harnessed by Japanese Americans in the late 1960s, taiko's sonic largesse and buoyant energy challenged stereotypical images of Asians in America as either model minorities or sinister foreigners. While the majority of North American taiko players are Asian American, over 400 groups now exist across the US and Canada, and players come from a range of backgrounds. Using ethnographic and historical approaches, combined with in-depth performance description and analysis, this book explores the connections between taiko and Asian American cultural politics. Based on original and archival interviews, as well as the author's extensive experience as a taiko player, this book highlights the Midwest as a site for Asian American cultural production and makes embodied experience central to inquiries about identity, including race, gender, and sexuality. The book builds on insights from the fields of dance studies, ethnomusicology, performance studies, queer and feminist theory, and Asian American studies to argue that taiko players from a variety of identity positions perform Asian America on stage, as well as in rehearsals, festivals, schools, and through interactions with audiences. While many taiko players play simply for the love of its dynamism and physicality, this book demonstrates that politics are built into even the most mundane aspects of rehearsing and performing.

Description : Moving Otherwise examines how contemporary dance practices in Buenos Aires, Argentina enacted politics within climates of political and economic violence from the mid-1960s to the mid-2010s. From the repression of military dictatorships to the precarity of economic crises, contemporary dancers and audiences consistently responded to and reimagined the everyday choreographies that have accompanied Argentina's volatile political history. The titular concept, "moving otherwise" names how both concert dance and its off-stage practice and consumption offer alternatives to and modes to critique the patterns of movement and bodily comportment that shape everyday life in contexts marked by violence. Drawing on archival research based in institutional and private collections, over fifty interviews with dancers and choreographers, and the author's embodied experiences as a collaborator and performer with active groups, the book analyzes how a wide range of practices moved otherwise, including concert works, community dance initiatives, and the everyday labor that animates dance. It demonstrates how these diverse practices represent, resist, and remember violence and engender new forms of social mobilization on and off the theatrical stage. As the first book length critical study of Argentine contemporary dance, it introduces a breadth of choreographers to an English speaking audience, including Ana Kamien, Susana Zimmermann, Estela Maris, Alejandro Cervera, Renate Schottelius, Susana Tambutti, Silvia Hodgers, and Silvia Vladimivsky. It also considers previously undocumented aspects of Argentine dance history, including crossings between contemporary dancers and 1970s leftist political militancy, Argentine dance labor movements, political protest, and the prominence of tango themes in contemporary dance works that address the memory of political violence. Contemporary dance, the book demonstrates, has a rich and diverse history of political engagement in Argentina.

Description : In the past decade, Vancouver dance has received tremendous acclaim nationally and internationally, as witnessed by the success of choreographer Crystal Pite and a rejuvenated Ballet BC. But this is only part of a vibrant and diverse story of contemporary movement practices in the city. In My Vancouver Dance History Peter Dickinson crafts an embodied narrative that focuses on his critical and creative collaborations with nine Vancouver-based dance artists and companies. Mixing interview excerpts with fieldwork descriptions of studio research and performance analysis, Dickinson draws on ten years of close observation to delve into the individual histories of select members of this community, while also relating the cumulative story of Vancouver dance production and performance as it has unfolded in the past decade. The voices of other invested participants interpolate this rich history, and chapters are interspersed with a series of "movement intervals" that reflect key moments in Dickinson's history as a spectator, scholar, and collaborator. In innovative ways, Dickinson suggests that when we pay attention to the larger social topography of dance practice - the sites that give rise to it, the labour that goes into it, and the professional friendships it engenders - we can properly understand dance's contributions to civic life.

Description : The Routledge Companion to Dance Studies maps out the key features of dance studies as the field stands today, while pointing to potential future developments. It locates these features both historically—within dance in particular social and cultural contexts—and in relation to other academic influences that have impinged on dance studies as a discipline. The editors use a thematically based approach that emphasizes that dance scholarship does not stand alone as a single entity, but is inevitably linked to other related fields, debates, and concerns. Authors from across continents have contributed chapters based on theoretical, methodological, ethnographic, and practice-based case studies, bringing together a wealth of expertise and insight to offer a study that is in-depth and wide-ranging. Ideal for scholars and upper-level students of dance and performance studies, The Routledge Companion to Dance Studies challenges the reader to expand their knowledge of this vibrant, exciting interdisciplinary field.

Description : "Corn is made mostly of soil moisture and warm air. The acre yield of the United States has been below 31 bushels every year, while moisture and warm air sufficient to bring the yield to 100 bushels have gone to waste. By reducing the waste of moisture and heat corn yields can be doubled. Moisture runs off and carries with it the most fertile parts of the soil. Heat goes to waste in drying the soil and subsoil while timely cultivation would save both heat and moisture. Cultivation sometimes is beneficial, sometime injurious. Page 18. Recent discovery of the fact that seed corn that matures well and dries out promptly will keep its good germinating and yielding powers for four or five years makes unnecessary planting of poor seed corn or the loss of acclimated and improved strains. Page 23. This bulletin is especially applicable to dry-land regions; but corn yields are so dependent upon the relative quantities of soil moisture and heat that the principles given here apply wherever corn is raised." -- p.

Description : It's not a mystery, it's a story of survival and triumph. That's what some people say about Romance, a would-be hit play about an actress pursued by a knife-wielding stalker. But isn't it romantic! Before the show can open, the leading lady is really attacked, outside the theater. And before the detectives of the 87th can solve that crime, the same actress is stabbed again. This time for keeps. A.D.A. Nellie Brand moves in for a murder conviction, but Detective Steve Carella is sure she's got the wrong guy, and wrestles for the case with Fat Ollie Weeks, Isola's foulest cop. While Bert Kling interviews witnesses and suspects ranging from the show's producers to the author - who has written novels about cops and knows how it's done - to the lead's lovely understudy, he can't keep his mind off what's happening to him. He's falling in love. With a doctor. Who happens to be a deputy chief surgeon. Who happens to be a black woman. In the city of Isola, nothing is black and white. In the play Romance, no one is guilty or innocent. And in the gritty reality of the 87th Precinct, everyone is in love with something - even if it's only murder.

Description : Production of Portland cement is responsible for about seven percent of the world’s greenhouse gas emissions. The pressure to make the production of concrete more sustainable, or "greener", is considerable and increasing. This requires a wholesale shift in processes, materials and methods in the concrete industry. Pure Portland cement will need to be replaced by more complex binary, tertiary or even quaternary binders, including other types of cementitious materials. We can expect an increasing use of high performance concrete, primarily because of its high sustainability and durability. Much more attention will have to be paid to the proper curing of the concrete if we want to improve its life expectancy. Presenting the latest advances in the science of concrete this book focuses particularly on sustainability, durability, and economy. It explores the potential for increased sustainability in concrete from the initial mixing right through to its behaviour in complex structures exposed to different types of loads and aggressive environments.

Description : Curing is one of those activities that every civil engineer and construction worker has heard of, but in reality does not worry about much. In practice, curing is often low on the list of priorities on the construction site, particularly when budgets and timelines are under pressure. Yet the increasing demands being placed on concrete mixtures also mean that they are less forgiving than in the past. Therefore, any activity that will help improve hydration and so performance, while reducing the risk of cracking, is becoming more important. Curing Concrete explains exactly why curing is so important and shows you how to best do it. The book covers: The fundamentals behind hydration How curing affects the properties of concrete, improving its long-term performance What curing technologies and techniques you can use for different applications How to effectively specify, provide, and measure curing in a project The author also gives numerous examples of how curing—or a lack of it—has affected concrete performance in real-world situations. These include examples from hot and cold climates, as well as examples related to high-performance concrete, performance parameters, and specifications and testing. Written for construction professionals who want to ensure the quality and longevity of their concrete structures, this book demonstrates that curing is well worth the effort and cost.

Description : The Crack in The Halo follows the harsh journey of ten young Irish women who entered a religious institution in Ireland in 1966 to prepare themselves for a life of dedication and service. Their experience of life in the convent proved to be challenging from the beginning, as they faced bullying and discrimination perpetuated by an authoritarian and dictatorial system of governing there. Several of them developed ways to cope despite the hardship. Others were not so lucky. One found herself on a road to experiences she had never imagined. The nun in charge of the ten “postulants” put them through a daily crucible of cruelty, invoking severe punishment for the smallest perceived infraction. Only the strongest emerged intact after their grueling time in this unhealthy environment. This story is one that reverences the memory of so many nuns who went to their graves as victims of abuse.

Description : The report comprises a review and analysis of the available literature pertaining to the causes, effects and prevention of secondary (delayed) ettringite in concrete . Over 300 publications have been examined . Case studies of damage in concrete possibly caused by secondary ettringite formation are examined first. Fundamental research on secondary ettringite formation, its chemistry, and deposition mechanisms is then reviewed. Key investigations on the topic are analyzed in detail. Next, the potential importance of (a) method of heat-curing and (b) the chemistry of cement is outlined. In the final chapter, a rapid test for evaluation of potential secondary ettringite susceptibility (the "Duggan" test) is evaluated. The analysis indicates that there appears to be a potential for a secondary ettringite formation problem in North America; it is highly probable that secondary ettringite formation can lead to significant deterioration of heat-treated concrete. However, it is unlikely that secondary ettringite formation is, or will be, the sole mechanism responsible for premature deterioration. The critical factors that determine extent of damage due to secondary ettringite formation are (a) duration of delay period before heating the concrete; (b) severity of the heating and/or cooling regime ; and (c) the SO3/A1203 ratio of the cement. There is no evidence that nonheat-treated concrete is susceptible to this phenomenon. Further research and improvements to the Duggan test may result in the development of a useful standard test method to assess the long-term dimensional stability and durability of concrete.
